Summary

In this research, flat-heat-pipe heating system using phase change material (PCM) and thermoelectric unit was firstly proposed. The flat heat pipe was utilized as a heating terminal in this system, which made it have potential to achieve intermittent radiant heating for specialized applications. Furthermore, the proposed system would be able to use solar energy to achieve a higher energy efficiency owing to the integrated PCM. In addition, the thermoelectric unit, which acted as an auxiliary heat source, was innovatively integrated with PCM and flat heat pipe. This structure increases the heating coefficient of performance of thermoelectric unit and makes it possible to apply the thermoelectric unit in the field of heating. The different components of the heating system complemented each other and meant that intermittent heating could be achieved at any time. The experimental results show that the heating terminal could be heated in only 500 s. Moreover, the PCM was able to guarantee a heating temperature above 40 °C for 2520 s. When the heat supplied by the PCM was insufficient, the thermoelectric unit provided the needed heat with a coefficient of performance greater than 1.70. In addition, the thermoelectric unit had a heating coefficient of performance of 1.35 to 1.54 when there was no heat stored in the PCM. Overall, this novel heating system is capable of highly efficient intermittent heating.
